HENRY BAUCH AND HARRY E. RAUCH, OF MOUNT VERNON, NEW YORK. q

CASK-PITCHING MACHINE.

T0 all whom t may concern Be it known that we, HENRY RAUCH and HARRY E. RAUCH, citizens of the United States, and residents of Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Cask-Pitching Machines, of which the following is a specication.

Our invention relates to apparatus employed for the purpose of applying hot liquid pitch or the like to the interior surfaces of beer barrels, easks,"&c., and has for one of the principal objects to provide such an apparatus which shall be safe in operation; the invention being an improvement upon apparatus of the type set forth, for instance, in United States Letters Patent No. 599,476', granted to Henry Rauch on February 22, issie.

An apparatus of the type which is the subject of the said Letters Patent No. 599,476 and of the present invention is designed to be operated by compressed air or similar means, which is admitted into the pitch receptacle and which forces the hot liquid pitch out through a spraying nozzle into the interior of the cask or other vessel which is to be interiorly coated or pitched. Tn using such an apparatus it sometimes happens that a careless workman will turn on the compressed air when there is no barrel over the spraying nozzle, or will attempt to lift the barrel o the nozzle without shutting ofi' the compressed air, thus allowing a quantity of hot pitch to be sprayed about the room, severely burning anyone within range of the spray.

@ne of the objects of our present invention is to provide means whereby the stop cock controlling the compressed air can only be opened when there is a barrel over the spraying nozzle.

The invention consists in the novel construction, arrangement and combination of various devices and parts as shown in the accompanying drawings and fully described in this specication.

Tn the accompanying drawings, Figure 1 is a sectional view of a pitching apparatus provided with our invention; Fig. 2 is a sectional view of a modified form of our invention adapted to be used with a pitching apparatus in which the handle controlling the compressed air stop-cock is moved in a horizontal, instead of a vertical plane, as shown in Fig. l; and Figs. 3 and 4 are detail specicaaon of Letters raient. i Pawnee@ B90, 29, 1914, Application filed March 30, 19x14. Serial No. 828,416.

plan views of a portion of the mechanism shown in Fig. 2, which are hereinafter more particularly described.

The main features of a Cask pitching apparatus to which our present invention is applied are fully described in the said Letters Patent, No. 599,476, and need not be specified in detail here and it will be suiicient to state, (referring more particularly to Fig. 1 of the present drawings), that 11 represents the kettle or reservoir to contain the pitch, which is mounted over a suitable furnace for heating the same.

Below thebottom of the reservoir or kettle 11and preferably integral therewith is a tank 12, having an inlet 13 adapted to permit the flow of pitch from the reservoir 11, said inlet being controlled'by a suitable valve opening downwardly or inwardly at 13.

A pipe 14 leading from some suitable source of compressed air or the like enters the top of the tank 12 and from a point near the bottom of the tank 12 an outlet pipe 15 extends upward through the receptacle 1l and bears at its upper end a perforated spraying nozzle 16. It will be readily understood that when the'machine is operated, the tank 12 being full of liquid pitch, if compressed air is admitted through the pipe 14 it Awill eXert pressure upon the upper surface of the pitch in the tank 12, forcing the same out through the pipe 15 and spraying the same into a barrel 17, which rests, during the operation, upon a suitable support 18, the pipe 15 extending upward through the bunghole. The liquid pitch covers the inner surface of the barrel, and the surplus drains down through the bunghole and iiows into the receptacle 11.

The supply of compressed air is regulated scribed, at the same time keeping the valve 1 13 closed against the weight` of the pitch in the tank 11. When, however, the lever 2O is in the position shown in the full lines, the supply of compressed air is cut off and the tank 12 is in communication through fl. 1 O

in the drawings); and the safety device, hereinafter described. In carrying our invention into eifect in this embodiment we provide a support 44, analogous to the sup-` port 23 of Fig. 1. On this support are pivotally mounted levers 46 adapted to assume the position shown by the dotted lines when barrels are placed on the supports 41, but otherwise adapted by the weight of their upper portions (designated 45) to assume the position shown by the full lines. The upper end of the rod 43is journaled in a stationary guide 47, which is also provided with slots 48 in which the levers 46 may slide as a barrel is lifted on or removed from one of the supports 41. Rigidly mounted on the rod 43 is a projecting pin extending between the levers 46 and adapted, when both of these levers are in the position shown by the full lines, to prevent the rotation of the rod 43 inveither direction. When, however, one of the levers 46 is in the position shown by the dotted lines, the rod 43 can be rotated in one direction, as the pin 49 will clear the lever when it is placed in such a position.

rIhe operation of this embodiment of our invention is as follows: When the machine is not in use the levers 46 remain in the position shown by the full lines and the handle 42 cannot be moved. When, however, a barrel is placed upon one of the supports 4l, the lower end of the lever 46 situated on that side of the machine is depressed, thus allowing the handle to be turned and the compressed air to be admitted to the tank which is situated under such support 41, and the barrel placed thereon to be sprayed. As long as the compressed air remains turned on, the barrel can not be lifted from the support, as the handle 42 is directly thereover. As soon, however, as the compressed air is shut off, the barrel may be` lifted as the handle 42 is no longer in the way. As soon as the barrel is lifted off, the lever 46 reassumes the position shown by the full lines, and the device remains locked until another barrel is placed upon one of the supports 4l.

Fig. 4 shows a modified form of the parts shown in Fig. 3. A handle and upright rod 6l are provided, analogous to the handle 42 and rod 43 shown in Fig. 3. In Fig. 4, however, instead of one pin 49, two pins 62 and 63 are shown, and two guides 64 and 65 placed some distance apart, instead of the guide'47 of Fig. 2.

The advantages of our invention will be obvious from what has been above said concerning its construction and mode of operation.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is as follows: A

l. In a safety device for pitching Inachines,the combination with a pitching machine of the type operated by compressed air or the like, of a lever having one end adapted to be depressed by a barrel or the like placed thereon, and having its other end provided with a notch, means adapted to control the compressed air which operates the machine, a lever adapted to operate said means, one portion of said lever being adapted to engage with said notch, and means operatively connected with another portion of said lever, and adapted to move the same and thereby control said compressed air, said means comprising a bar pivotally connected to said second named lever, and an L-shaped lever pivctally connected to the other end of said' bar.

2. In a safety device for pitching machines, the combination with a pitching machine of the type operated by compressed air or the like, of a lever having one end adapted to be depressed by a barrel or the like placed thereon, and having its other end provided with a notch, a lthree-way cock adapted to control the compressed air which operates the machine, a lever adapted to operate said three-way cock one portion of said lever being adapted to engage with said notch, and means operatively'connected with another portion of said lever and adapted to move the same and thereby control said three-way cock, said means comprising a bar pvotally connected to said second named lever, and an L-shaped lever pivotally connected to the other end of said bar.

In witness whereof we have hereunto signed our names this 27th day of March 1914, in the presence of twol subscribing witnesses.
